Maruha has designed the Long Vacuum Brake Booster Hose as a one-size-fits-all solution for all MX-5 NA NB cars. Some of the original booster hoses are becoming hard to find as production has ended. This part replaces all booster hoses found on the Mk1 and Mk2 MX-5 and is intended to be trimmed if required. The additional length is particularly useful when attaching to a vacuum manifold on a car with Individual Throttle Bodies, or when swapping in different engines. The hose includes a one-way valve to ensure correct operation of the brake booster. Features Extra length for ITBs and engine swaps Can be trimmed to size where required Integrated one-way valve for correct booster operation (arrow indicates manifold side)
